PEA FAMILY. Fabaceae. 
There are several kinds of Thermopsis, of North America 
and Asia; stout, perennial herbs, with woody rootstocks; 
leaflets three; stipules conspicuous, leaf-like; flowers large, 
yellow, with short, bracted flower-stalks; calyx bell-shaped, 
five-cleft; standard broad, in the western species, shorter 
than the oblong wings, keel nearly straight, blunt, the 
same length as the wings; stamens ten, separate, curving 
in; style slightly curving in, stigma small; pod flat, long or 
oblong, straight or curved, with a very short stalk and 
several seeds. Thermopsis, sometimes called False Lupine, 
is distinguished from Lupinus by its stamens, which are 
separate, instead of united into a sheath. The Greek 
name means “lupine-like.”’

Pe are silky and also the calyxes and buds. 
This thrives in the mountains, up to an 
altitude of nine thousand feet, in somewhat moist spots, 
and its fresh coloring is most attractive. The foliage seems 
to me to be especially handsome in northern Arizona, but 
these plants are also beautiful in the Utah canyons. The 
flowers are scentless and last a long time in water. T. 
Californica has silvery, silky~foliagé and is common in 
California, in damp ground in the hills. 
There are many kinds of Parosela, of western North 
America, Mexico, and the Andes, no one sort common; 
generally shrubs; leaves almost always compound; leaflets 
odd in number, small, toothless, with minute stipules, 
often with glandular dots; flowers small, in terminal clus- 
ters; calyx with nearly equal, long, occasionally feathery 
teeth; corolla with wings and keel longer than the standard, 
their claws adhering to the lower part of the stamen-tube, 
but the claw of the small, heart-shaped standard free; 
stamens nine or ten, filaments united, anthers alike; ovary 
with a short stalk, or none, style awl-shaped; pod small, 
membranous, included in the calyx, usually with one seed. 
P. spinosa, the Smoke Tree, or Ghost Tree, of western 
Arizona, is almost leafless, with grayish or whitish branches.
